Monitoring coagulation tests is an important nursing function.
Evaluating a patient's coagulation status helps the nurse to recognize the
potentially life threatening consequences of homeostatic imbalance, including
excessive bleeding or thrombus formation. In addition, coagulation tests such as
the prothrombin time ( PT ), partial thromboplastin time ( PTT ), and the activated
clotting time (ACT) are frequently used to monitor the effects of anticoagulant
drugs.This web page uses frames, but your browser doesn't support them.
